Objective:The development of associated febrile to lymphadenomegaly leads to several diagnostic hypotheses, among them the Kikushi-Fujimoto disease.Method:This review was set up by searching PubMed/Medline, Web of Science and Scopus database using the following key words: "Kikushi disease", "Kikuchi-Fujimoto disease", "histiocytic necrotizing", "lymphadenitis","lymphadenopathy". Results:We report a case in a young patient with a fever associated with the emergence of adenomegaly and weight loss in two months, associated with hepatosplenomegaly. In laboratory tests showed anaemia with erythrocyte sedimentation rate (ESH) and lactate dehydrogenase (LDH) test elevated, widened mediastinum, with bilateral pleural effusion. Conclusion:Excisional biopsy of supraclavicular lymph node showed Kikuchi-Fujimoto disease on microscopic examination. After histopathological confirmation, were other causes of febrile adenomegaly apart, starting dose corticosteroid immunosuppressive therapy.
